The results of researches on clearing of chrome containing of wastewater by an electrodischarge method are represented. The experiments were carried out on low-voltage (up to 550 W) and high-voltage (up to 17 kW) installations. The principle of clearing of water from hexavalent chrome is based on its reducing by bivalent iron ions which are generated under electrical discharge between metallic particles in an aqueous medium with further precipitation of the chrome (III) ions and iron hydroxides. It has been shown, that the investigated method allows to achieve the concentration of chrome in water that is not exceeding of values of marginal concentration. Thus energy efficiency of the given method is lower in 2 times in comparison with electrolysis one at identical consumption of coagulant. |
